The DBH 9661 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Its compact size makes it suitable for equipment where axial space is limited and a reliable barrier is needed. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is a seal with an A 276 design and the following dimensions: shaft diameter 12 mm, housing diameter 20 mm and height 9.00/11.00 mm. That variable height means the seal can sit in cavities between 9 and 11 mm without losing sealing performance. The lip runs on the rotating shaft and the outer case stays fixed in the housing. Always confirm these dimensions against the drawing or the original part before ordering.

Seals of this size are found in small electric motors, gearboxes, water pumps, fans, pneumatic tools and light transmission equipment. They also appear in agricultural machinery, washing equipment and irrigation systems where small-diameter shafts rotate at moderate speed. In all these cases the function is the same: keep oil or grease inside and contaminants outside.

To select a seal correctly, in addition to the three dimensions, take into account shaft speed, working temperature and the type of lubricant. The A 276 design corresponds to a standard single-lip profile with a spring, suitable for shafts with a good surface finish. If the shaft is scored or has play, the seal will not perform: it is best to check the condition of the shaft and the housing before mounting.
